Geranium 'Orion' has beautiful mid blue flowers. It is a tall clumping perennial, (USDA Zones 5 - 9), 24-30 x 36". It does well in full sun in mild summer gardens and morning sun/afternoon shade in hot summers. It can be combined with roses, iris, ornamental grasses and summer bulbs. It needs a horticultural corset when young, (twigs help support it until the clump size increases). See Page 166, The Plant Lovers Guide to Hardy Geraniums. (Photo by Donn Reiners)
